Test Results: Sumeike, Precise & SoBong…Part 3 - SoBong

Here are the results for Precise 3rd Generation 0.40 to 0.75.

Column 1 = Band cut with ball bearing ammo size.

Column 2 = Average speed in Feet Per Second (FPS)

Column 3 = Draw Weight in pounds (lbs), exactly as it appears on the digital luggage scales.

Column 4 = Temperature indoors, which was always the same.

I don't include the actual length of the band in the results for 2 reasons.

1). We all have different draw lengths.

2). The band length could be 10mm or more out because of the natural stretch increase over time.

Besides, we all know when we have pulled the band to or close to maximum stretch.

Based on this set of data, I can now create an endless amount of lists.

Now, remember that fun day that I mentioned, where I just want to smash cans with a heavy setup and I don't care about band life.

Well, I can use these band results just as they are, or even reduce their active length a tiny bit more for even more power.

The following 4 lists give me an IDEA of the power potential offered by the 4 different sized ball bearings.

Now, if I want to do the same again, but this time I only want to focus on straight band cuts for some reason,

then the following 4 lists give me an IDEA of the power potential offered by the 4 different sized ball bearings.

Ammo - 6mm - FPS FOR TOP 6 STRAIGHT BAND CUTS

289 5/8 - 5/8 12.47 0.65

288 7/8 - 7/8 15.97 0.70

287 1/2 - 1/2 12.25 0.65

287 30 - 30 13.54 0.40

285 1 - 1 15.76 0.60

284 1 - 1 12.48 0.40

Ammo - 7mm - FPS FOR TOP 6 STRAIGHT BAND CUTS

278 1 - 1 15.76 0.60

278 7/8 - 7/8 15.97 0.70

274 5/8 - 5/8 12.47 0.65

273 30 - 30 13.54 0.40

273 1 - 1 12.48 0.40

273 7/8 - 7/8 13.91 0.60

257 30 - 30 13.54 0.40

257 3/4 - 3/4 13.91 0.65

257 1 - 1 16.88 0.70

253 7/8 - 7/8 13.91 0.60

Ammo - 9.5mm - FPS FOR TOP 6 STRAIGHT BAND CUTS

242 7/8 - 7/8 15.97 0.70

239 1 - 1 16.88 0.70

230 30 - 30 16.04 0.60

230 1 - 1 15.76 0.60

230 7/8 - 7/8 13.91 0.60

229 30 - 30 13.83 0.50

Remember when I said that I could also use this set of data to search for light setups too?

Well, I can find the lowest draw weight results and then simply increase the active length until I achieve my desired results for a combination of power,

draw weight, ball bearing size, and of course, band life.

We have 2 more lists below just for that very purpose.

Ammo - 6mm - FPS FOR DRAW WEIGHTS OF 7 AND BELOW

253 5/8 - 1/2 6.65 0.45

234 1/2 - 3/8 6.29 0.45

227 1/2 - 1/2 6.30 0.45

203 3/8 - 3/8 6.52 0.40

210 3/8 - 3/8 5.49 0.45

Ammo - 7mm - FPS FOR DRAW WEIGHTS OF 7 AND BELOW

232 5/8 - 1/2 6.65 0.45

213 1/2 - 3/8 6.29 0.45

212 1/2 - 1/2 6.30 0.45

200 3/8 - 3/8 6.52 0.40

196 3/8 - 3/8 5.49 0.45

Once again, you may experience a slight increase in power when compared to my set of data.

Firstly, for all my testing, I used an over sized pouch which was really meant for 10 - 13mm ammo.

This was the only pouch I had which had big enough holes to fit all the different thicknesses of latex band.

All my other pouches had tiny holes. These pouches would have made me give up on the testing project very quickly.

Secondly, I did not cut the 10mm or so excess latex from the pouch end. This enabled me to re-use the latex.

Now, if you are still interested, you can move onto Test Results: Sumeike, Precise & SoBong…Part 3 - SoBong

Hey Guys,

AKA Forgotten - You are very welcome. I thanked you further in Part 3.

Kalevala - Yes, you understand that this is all about ideas.

If people already have this brand of latex, then the set of data can give you an IDEA of how to get the most out of it.

It can also help to give you an IDEA of which thickness you may want to buy and try.

As well as which thickness you may wish to avoid, therefore saving you some money.

By the way Kalevala, I am a big fan of your videos.

Because of this, I reached out to you a little while ago on one of your youtube videos, and you were kind enough to reply.

So I am glad you have shown an interest in the threads and that they have given you some ideas.

Many thanks for typing all the info and data in the 3 posts. Much appreciated! I know that it must have taken a lot of time. Even the small amount that I post takes more time than you would think. I plan to save all your numbers for future reference. I'm always after top performance with a low draw weight. You saved me lots of time!

Hey Northerner,

I have noticed that you have posted some great band testing information yourself.

I really just copied and pasted the numbers on to the thread to save time.

I tried to do the same on Slingshot Community too, but it just came out a big mess of numbers all bunched together.

So I just gave up on that site. I had absolutely no trouble on this site.

You say that you plan to save all my numbers for future reference.

Well, let me save you the trouble...I left you a gift below...just in case the threads mysteriously disappear in the future.

Excellent! Now I can lay some numbers side-by-side on papers and do easier comparisons. I'm a bit of a numbers addict so this stuff is like diamonds to me.

Thank you, SStallion...More and more my primary interests for shooting are draw weight and matching my ammo to bands.

These data sets just removed a bunch of the trial & error for me.

I am still not settled on a particular brand of elastics...Nit wvwn settled on tubes or bands.

I do prefer tubes if I am backpacking. Easier to maintain & switch out.

For me shooting light is the most fun.

Again much appreciated.

AKA Forgotten - You are welcome.

Northerner - Yes, I thought it would be much easier if you had the documents.

Flatband - I hope you can make use of the sets of data.

(Todd?)

MakoPat - Yes, you are right about removing the trial and error.

This set of data can help people save time and money on latex.

It can help guide you in choosing the correct thickness for your own testing.

It can also help guide you in which thickness to stay away from.

IMPORTANT - I just posted a reply to Projectile Pilot in Part 1.

He correctly posted that his results for Sumeike 0.70 were about 30 FPS faster than mine.

I have copied and pasted my reply below for you all to remember:

Yes, that sounds about right.

Remember, my results are for a 30.5 inch draw, so I would expect your 32 inch draw to get faster speeds.

I would also expect someone with a 34 inch draw to get even faster speeds.

That is why someone on this forum gets 300 FPS with 9.5mm ball bearings using full butterfly. (Not Sumeike)

It's because his draw length is longer still.

For a shorter draw, I would expect all the FPS results to move lower together.

For a longer draw, I would expect all the FPS results to move higher together.

And I would also expect the 23 band cut results to remain more or less in the same order too.

I really appreciate your tests, which are far better than what I have seen in the past 2-3 years.

At this time they are the best reference you can find on Summeike/Precise/Sobong at your draw length of 30.5 inches.

I only hope that the results increase linearly with the draw length.

In other words for the same elastic brand/thickness/ammo but with a longer draw length the speed ratios will stay more or less the same.

It would be great if you could repeat the tests for a draw length of 40, 50 and 60 inches (just kidding since that would take you the entire next week).

Hey Guys,

Northerner asked me a great question in Part 1, so I wanted to post the reply in Part 2 and Part 3 aswell, just in case anyone missed it.

He wrote:

Secretstallion....have you compared your freehand shooting to the machine shooting numbers? It would be interesting to see a few examples. I'm curious if the freehand produces a bit higher numbers. A machine release is completely dead. Freehand shooting can produce a bit more power from an active release and/or a frame flip.

Hey Northerner,

Yes, you are correct in suggesting that freehand slingshot FPS numbers may be slightly higher than testing rig FPS numbers.

I found that when I shoot freehand over a chronograph, I subconsciously try to cheat or 'push' the FPS numbers higher.

This may include drawing back a little further, releasing the ball bearing straight away instead of waiting about 2 seconds like I would do

in real life for aiming purposes and flicking my wrist forward upon release.

So the problem with using freehand is that I could not trust my results because there was no consistency.

I could not replicate these little cheats exactly the same every single time, especially when I don't always know that I am doing it.

This is the whole reason I chose to use the testing rig.

So, like I mentioned in the thread, I used the testing rig to solve these problems and guarantee consistency in my results.

I could not cheat by drawing back any further than 30.5 inch.

I could not cheat by flicking my wrist forward.

And I released the ball bearing 2 seconds after loading which is exactly what I do when I shoot freehand.

Which means my testing rig release is not completely dead as you suggest, because that would also have to mean that my freehand shooting

is completely dead too, because it is the exact same 2 second hold before pouch release.

I mentioned in the threads that you should not be surprised if you get higher FPS numbers when compared to those shown in the set of data.

I mentioned I use an oversized 10-13mm testing pouch and I do not cut the excess 10mm or so of latex from the pouch end.

Well, when you throw in those little cheats I mentioned, you can see why you can achieve higher FPS numbers than those shown.

This is why I kept repeating that this is an IDEA of the FPS, etc.

As an example, once I finished all of my testing, I then cut a 3/4 - 3/8 Sumeike 0.45 band set and then attached it onto my freehand slingshot.

But this time, instead of using an oversized testing pouch meant for 10-13mm, I used a small aerodynamic pouch meant for 6-7mm ball bearings.

This time I also removed the 10mm or so excess latex from the pouch end. I then shot a 6mm ball bearing.

My set of data showed 255 FPS. This time, however, 301 FPS appeared on the chronograph, but I was not surprised.

It was a combination of using the correct sized pouch, removing the excess latex, inconsistent draw length, inconsistent pouch release

and subconscious flicking of the wrist to push my numbers higher.

So my testing rig ensures me consistency in results when comparing FPS, band thickness, band cuts, draw weight and ball bearing size.

The set of data gives you an IDEA of what to expect when using my exact set of test criteria.

You can either enjoy the slightly higher FPS that you may achieve when using the appropriate pouch and shooting freehand,

or you can choose to use a combination of band thickness, band cut, draw weight and ball bearing size to achieve your desired results.

The set of data is the starting point, the rest is where the fun starts.

I am glad you asked this great question because it gives me a chance to add this information just in case someone else is wondering the same thing.

I shall post this on the other 2 comment sections because it is such a great question.

Very useful info. I can now cut my bands to the right DW n speed. I did some minor adjustments like using 22/12 instead of 22/10. Thank you for all your trouble
